Answer:

The constant of proportionality is [tex]\frac{9}{4}[/tex].

Step-by-step explanation:

Given : The equation [tex]4y = 9x[/tex] represents a proportional relationship.

To find : What is the constant of proportionality?

Solution :

The  proportionality relationship is [tex]y=kx[/tex]

where, k is the constant of proportionality

Re-write the equation in the required form,

[tex]4y = 9x[/tex]

Divide both side by 4,

[tex]\frac{4y}{4}=\frac{9x}{4}[/tex]

[tex]y=\frac{9}{4}x[/tex]

Therefore, the constant of proportionality is  [tex]\frac{9}{4}[/tex].

Answer:

b: 9/4

Step-by-step explanation:

4y = 9x → y = 9/4 x; thus, 9/4 is the constant of proportionality.
